Mounte ed onlhoriz ontal rods I1 and 161s a base member |9 -which supports-motor 26 and is secured there'- r to by any suitable means such as stud bolts 2 I. A

suitable pulley 22' is mounted on motor which isadapted toldrive astill larger pulley 24 by any This pulley 2 4 is fixedly mounted on rotatable shaft 25 46 supported at its ends by bearings invertical memcured to vertical members 29; by means of horizontal members 28 and straps 21 also "secure said bers 26, The upper ends of members 26 are semembers 26 toverticalmembers 29 (Figs. 1; 2- and l 3) .f :Moimted on supports 26 and on'table member ,M supported by jsupports ln, H; and .12, is a-table V 36' serving as a slide for cartons and-the like after the same have been closed. lMount'e'd' on 'supports 29 isa table3l. which is adapted to receive I tion' 3|c secured to a suitable cross member 26a the sealedcartons. ,Table 3| is slightly elevated above table or s1ide30. is an'apron having a horizontal portion 3|a, an arcuate portion 3J1) and a second horizontal pordisposed between supports 26.' j l f Upon rotatable shaft 25 is fixedly mounted a 7 small pulley 32 which is adaptedby means of a suitable belt 33 to drive a still larger pulley '34,

it i 'fixed onshaft. 35 rctatably mounted in bearings V withalarger gear or pinion 36 todrive main drive 36 of members l0 and II. 35 is :a gear or pinion 31'whichis adapted to mesh shaft 39. a i a It is to be noted thatthe sizes and arrangement of the various pulleys are such that the revolutions'per minute of the'main shaft 39 havebeen' i reduced to a very much smaller number than that of the main drive shaft of the motor,

Shaft 39 is supported atone end by means of a suitable bearing 40 which is'atta'ched to table -member 4| by any suitable means such as bolts 7 42 and at the other end of shaft 39 is bearing 43' which also is attached to bottom portion of table member 4| by any suitable means such as stud bolt 44. {On the right hand end of shaft 39, Figure 2; is mounted a bevel gear 45 which is adapted Figure 26 is, a view similar to Figure 25;but

Extending from table 3| Fixed on said shaft to mesh with another bevel gear 46 mounted on' transversely disposed 'shaft4l. a I

On one end of shaft is mounted a sprocket chain 49, said sprocket chain being mounted on 7 smaller sprocket 50 to drive shaft 5|. Shaft 5| f is mounted in forked bearing member 52 (Figs. 2 and 5) which is attached to the lower portion Shaft 4'7 is mounted in bearings I03 and 41a,

said bearings extending upwardly and are fastened to sides of table member, by any suitable tively.

1 Nearthe center portion of shaft 5| is fixedly 1 mounted another sprocket 54:and this sprocket haschain 55 mounted thereon,'said chain having lugs 56 which are adapted to engage the cartons;

and'force them into the machine. The other end of chains 55 is mounted on sprocket 5'! (Figs. 1 and 4) which in turn is mounted on shaft 53 supported by forked bearing member 53 which is a of table member 4| by any suitable means such 'as stud bolts 53. V V 1 7 means such as stud bolts I030, and 41b respec slidably mounted on top of supporting member 3 r and has downturned portion 6|] and also stud bolt 6 I.' .It is evident that by turning stud bolt 6| adjustment can be-obtained and the chain 55 can be tightened to any desired amount.

Secured to the lower portionjof beam members 62 and63 of the conventional delivery mechanism for deliveringfthe filled cartons to'the folding u machine, are bearings and 65 having mounted therein a; shaft 65 with a roller 66 secured thereon which drives conventional conveyer belt 61.

Upon one end of shaft 65 ismounted sprocket l wheel 6811 which in turn has mounted thereon a sprocket chain 69a driven by any suitable source of power not shown. On conveyor 61 is shown a 7' plurality of cartons 68 containing a number of smaller packages 69. tons 68 may contain any suitable packages or materiaLthis machine is peculiarly designed for creasing and closing and sealing emen 0on taining packages of cigarettes.

Though it is evident car-- Each of these cartons as shown is closedl-oni 7 all sides except the top and has two projections Iii [and 'lfla integral with the ends andialso the side projection integral with one-sideof' the carton; Eachof said projectionswill'be creased ina mannerand' by mechanism to be later dee scribed; I

Itris evident that as roller 66 turns in a counter clockwise direction inFigure 3 4,. cartons 68 are forced upon table member 12 and between guide angles 13 and Hby means ofjlugs 56 onchain '55. "Table 12 has its upper surface in the same ends and project upwardly laterally and downwardly and'have secured at the rear side of the downwardly projecting portion a horizon: tally disposed guide strip 11.

Guide strip 11 at itsxright hand: end in Figure 1 V is flared outwardlyand downwardly over the path of the cartons in order to. allow projection ll of carton 68 to be guided by "strip 11'' in anupright position. The left hand end of strip '11 as seen in Figures 1 and 2 abuts against creasing bar I8 which has integral therewith curved supports 19 which project Ldownwardly and are secured to guide-angles I4 by any suitable means such as stud bolts 99.

A horizontally disposed plate 8|, rectangular in cross section, is secured to the side of guide angle I4 by any suitable means such as straps 82 and stud bolts 83, (Figs. 1, 2, 1'7 and 18). At the right hand end of plate 8|, as shown in Figure l, the end portion 84 is curved upwardly. This is done in order to allow the end projection 19a of carton 69 to be engaged by this upturned projection and forced to occupy a horizontal position to crease the same. This upturned portion 84 has longitudinally disposed slots 85 and 86 therein thru which prongs 81 and 88 pass when creasing member 89, bearing these prongs, oscillates to crease the other pro jection I9 of carton 68 as shown in Figure 1'7. The creasing of end projections 19a and I9 is done while the carton is moving thru the apparatus- Creasing member 89 is fixedly mounted at its upper end on a shaft 99 which is rotatably mounted in the upper end of bearing member 9|, which bearing member is supported by slide or table 4| and is secured thereto by any suitable means such as stud bolts 9Ia. Shaft 99 has fixedly secured on the other end thereof lug 92. Pivotally secured to lug member 92 as at 93 is a link 94 which is pivotally secured at its other-end to lever arm as at 96. Member 95 has integral therewith another arm 91 and both arms 95 and 91 are pivoted on pin 98 which is secured to table member 4|, (Figures 1, 2, 1'7 and 13).

On the lower end of arm 91 is mounted roller 99 which is adapted to engage cam I99 mounted on the end of shaft 41 and said roller isheld in close proximity to cam I99 by means of tension spring I9! which is secured to arm 91 as at I92 and to bearing I93 as at I94, The roller 99 is so situated on cam I99 as tocause member 99 to be in the act of creasing projection 19 of carton 68, just before the endof projection I9 comes in contact with upturned portion 84 of plate 8|. 7 v

As cam I99 rotates in the position shown in Figure 17, roller 99 which is normally held against cam. I99 by means of spring I9I and arm 9? are forced to the right and the free end of arm 95 and also link 94 are therefore forced upwardly which in turn forces member 89 to the left in order to crease the projecting member I9 of carton 98 and cause the free end of projection I9 to be guided beneath upturned lip 84,

In Figure 18 carton. 98 is shown in the position somewhat farther to the left after the projections I9 and 79a have been creased bythe corresponding mechanisms comprising prongs 81 and 89 and lip 84.

' It is to be noted that each lug member 56 when it reaches the position shown in Figure 18, on account of its being pivoted as at I95 to member I99 which is attached to chain 55 and on account of lug member 55 having a bevel surface on the upper end thereof, prevents the carton from being mutilated as it is moved to the left in Figure 18 as chain 55' moves on sprocket 54- as might happen in case this lug should not be beveled on the upper end and pivoted as at I95.

creasing angle I'I9 (Figs. 1 and 6') is secured to arms I II and 2 which are loosely mounted on shaft H3, said shaft II 3 being mounted for oscillation in brackets |I4"which are secured to guide angle I3 by any suitable nieans such as stud; bolts ||5-.' Arm I-'I-2-has-'a lateral projection II! which is 'adapt'ed'to r st against one of treesihg arms II8 to be later described, when the creasin'giar'rns are in raiseupositicn. JAt'Oi'SjOIl spring use is woun around shaft H3 and has one end secured to guide angle 13 and the other end is secured to member H2 This spring has a tendency to push 'n'imbeiS'I I I and I I2 together with creasin angle H9 to the right and against the brojctio'ri or lid 'II of carton 68 in Figure 6, Fixeclly securedo'n shaft I I3 between members II I and I I2 is the driving arm I29 with a bolt I2I in the free end thereof having a compression spring I23 mounted thereon. spring serves to lessen the impact imparted to creasing angle I I9 when shaft I I3 oscillates to cause bolt I29 to t'ap'the back of creasing angle I'Ill as shown in Figure '1. 1 s

Member. II2 also has a projection I22 whichis adapted to be engaged by pin IIB mounted ih shaft 3 to force creasing angle I|9 out of the path of projection II' of the carton as shown in Figure 6. Said members I and H2 are turn ably mounted on shaft I I3 and normall aS LiiIhe a position as shown in Figure 7 until pin IB 'engages projection I22 and forces these members back wardly as in Figure 6, whereas, arm I29 is fixedly mounted on shaft I I3 and is oscillated by the shaft. v M

Shaft I I3 is oscillated by having fixedly mounted thereon a projecting lug I25 (Fig. 9) which has pivoted in the upper end thereof as at I26 a link I21, said link I27 being pivoted a at I28 to the upper portion of L-s'ha'ped lever I29. ,Le ver I29 is pivoted on a shaft or pin I39 which is mounted in forked bearing I3I which turn is secured to table member 4| by any suitable means such Stud bolts I32. The lower end OfJL- Shaped member I2'9 has a roller I33 mounted thereon which is adapted to engage cam I34,

which is integral with cam sleeve I35 fixedly mounted on main drive shaft 39. A suitable spring I36 is attached to'angle guide I3 and also to the upper portion of L-s'h'a'ped lever I29 which normally holds the roller I33 on lower portion of lever I29 against cam I34.

In Figure 12 the cam I34 for "oscillating shaft 3 is shown in another position and in this position the shaft II 3 will be turned clockwise to cause the creasing device to assume a position as shown in Figure 7. 5

Mounted on shaft 3 is a horizontal bar I49 which has attached thereto a pluralityof creasing arms I I9 angular in shape which are" adaptedto oscillate'with' shaft I I3 being fixed thereon. The same movement of'shaft II3 that causes creasing angle I I9 to crease the top portion I43 of projection II of c'arton 68 along the line "Ild also causes creasing fingers I I8 mounted on bar I49 to simultaneously bend projection II along line MI in Figure 19 to cause it to assume a position Before this last described creasing operation is effected a plurality of evenerfinger's I45 are adapted to project thru holes I49 in angle guide I4 and engage the outside portion of a'c'arton 98 to press against the carton and even up the smaller packages 99.- When this operationtakes place asshown inFigure '13 and the evener fingers have withdrawn, it;will be notedthat an opening I41, between thejcigarettes or smaller; packages and the sidewall of the carton will be formed.

The opening 'I41 is formed because the inherent resiliency of the cartonmaterialtends to make' it the frictionbetween the walls of the chute to the cartons which have already passed the point where the sidewall of angle 14 isbeveled. ,This

opening I 41 will make room for the portion I43 of f projectionll whenthis projection is'creasedin -th'e position shown inFigure 12.

Evener fingers I45 have integral therewithla 3 horizontal bar I48 which holds these fingers together and saidbar member I48 has downwardly projecting members I49 which are fixedly mount-. ed on shaft 150.. Shaft I5Il'ismounted in bearings I5I. and I52 and" in turn these hearings are attached to the, bottom portion of table member Lby means of suitable stud bolts I53. Also secured roller I55 adapted to contact cam'I56 mounted on to shaft I50 is horizontally projecting barl54 (FigJlO) which has on the free end thereof cam cam sleeve I35;on' shaft 39. 'A suitable spring I51 is connectedto'an armrnember I49 and also to. the bottom portionofftable member 4I to normally hold arm I 54 down and to keepfcam roller I55'in contact with;cam I56. It should be noted that cam I 56 is so. made that when it'is revolved and thecam. roller engages notch portion I59- that a "slight tapping; effect will be" produced by-evener fingerssl45 onone sideof carton 68.

1 V Since-this operation precedes the creasingopera tion which takes place due to' fingers H8] and f guides I44,'the evener fingers must be out of the path of portion I43 before the fingers'I I8 are in position :as shown in Figure 12. The vertical leg 'on guide angle 14' is beveled on itssurface disposed next to the carton at this point in order to .adaptedto be inserted. V n Immediately followingthe creasing operation shown in Figure 12,- a holding device assumes the allow the front portion of carton 68 -to rest againstthis surface in order to 'form' a groove I41 between packages 69 and inside faced the carton in'to'which portion position shown in Figure 11. This holdingjdevice'ha's pins I60 which'a-readapted to project inmay'takeplacewhich'will be presently described.

triangularly cross sectionedplate- I42 land-to also hold portion I43 in slot I41 slightly above the closedposition in order that the gluing operation 5 This holding device has pins I60 attached in any suitable manner to fork members -I6I which have integral therewith a downwardly] projecting member I62.- This downwardly projectingrn'e'm ber I62 is turnably mounted on shaft I50 and has n integral therewith another arm I63 fwhichffpro- V j'ects horizontally toth-left as'shown in Figure show pins' ISIl in inoperative position. 'A suitable sprin'gfl66 .is attached'to downwardly projecting member I62 andlalso to bottom portion or table member 4| 7. t r ly. hold cam roller I64 against the surface of cam I 65.

: When this last creasing step; just described,

hastaken place the carton 68 is'forced out from I43 or carton is j beneath plns I66 and beneath thefinal closing device "I which holds the projection 1| and portion: I43 in a'positionshown in Figure 14'. A.cir-' cular disk n2 has beveled edge I13 and is adapted r ;to contact portion|43 of projection 1 I and a suitable adhesive isapplied to this portion of the carton. This disk I12 is adapted to rotate upon shaftl14 which ismounted in a suitable bearing I and has on the other endfthereof a gear 101 pinion I16 which is adapted to engage the gear I11 mounted on shaft I18, said shaftvln'be ing mounted in bearing I19 which projects downa wardly and is fastened to theside. portions of J I table member 4| by any suitableir'njeans such as stud bolt'sIBll'. It should benoted that the gear teeth in pinion-V I11 are parallel to the axis' of shaft I18, whereas, gear teeth in pinion I16 are angularly disposed but these gears mesh so that I the bearing I15, -.together withthe glue, pot I 90 can maintain another position to thefright as' shown in Figure 15;that 'is the slight variation.

in position of pinion I16 to the right or left-as might be caused by the action of camil presently to be described, will not "materially affect the'operation of the gears.

The other end of shaft I1 Bis mounted in bear ing I8I and has on the end thereof a bevel gear I8I is secured to lower portion of table member 4| by any suitable meanssuch as stud bolts I85.-

On the lower portion of shaft I84 is another bevel gear I86Iwhich' is adapted to mesh'with bevel gear I81 mountedon main'driveshaft 39. It is seen from Figure'l that asshaft 39 re 'volves, the movement is transmittedthru shaft 7' I84, beveled gears I82 and I83 and shaft I18 to 7 cause gear I11 to turn gear I16 and to cause the desired rotation to take place in-disk I12 to'apply adhesive to the portion I43 of carton 68.

Bearing I15 which has mounted therein shaft 114- for producing the rotation for the gluing operation is mounted on glue pot I90 by any suitable means such as stud bolts I9I. U V r Glue pot I90 is adjustably mounted on portion I93 which has vertically disposed member 194 integral therewith, said m'emben I94 being mounted on pin I95. Pin-1951s mounted in. v D V forked bearing I96, said bearing being secured to r wardly and hold the projection 1I' firmly against thebottom portion of table member 4| I V by any suitable means such as stud bolts I91.

' The lower portion of wheel I12 is always in.

contact with theglue or adhesive in glue pot I99 and this'causes the adhesive .to be'applied along the portion I43 as the carton is 'nfoved past wheel I12 by the next succeeding carton moving in a position to have its: lid moved to partiallyclosed position; V n V Vertically disposed member I94: has integral therewith inclined or angularly disposed member orarm I98 which has on the other end thereof 7 and wing nut 2B3 mounted on bolt 204 in Figure 14 that any, desired" adjustment canfbe made on the glue pot in'a horizontal lateral direction;

Sufficient portions from the top of guide angle 7 14 and table member M are cut away in order to secure the proper clearance for circular disk I12 aosncsa when-it moves to theleft in .Figure 14 to apply adhesive to projection I43.v

Figure 15 shows the position of the gluing.app'aratus after the carton 68= haspassed the-disk I12. After'thecarton passes the'disk H2 immediately' before :the final closing device orrectan'gular blade closes down upon portion H and forces portion M3 down into the carton to finally close-the package. Closing-plate I'll issecured to. members 2061' which members are loosely mounted on shaft H3; Spring 201 mounted on shaft ll3 normallyrholds members 206 andplate l1|= in the position shown in Figure:14. A pin 2G8- mounted in. shaft H3 is adapted to engage a projection onmember 1206: (Fig. 1) and. :cause the closing device to assume the position: as shown in Figure 15.

The. function of projection 209, pin 208 associatedwith spring: 201-, is identicalto that of spring 8a and projection: I22, together with pin H5 'in' Figure. 8. In the-.final' closing operation; however, theispring normally tends to hold the creasingdevice open and the pin when it engages projection 209 causes the closing device to operate, whereas, in Figure 8 the spring has atendency to cause theangle portion H fl to close and the pin: H6: when it engages projection. I22 serves to open-this member. After a carton 68 has been finally closedit is forced; by the other cartons to the extremei'lefthand end. of the machine as shown in'Figure 1, while package remover 2l0 is adapted. to' engage said. package to push it to the left in Figure 3..

Package remover; 210. pivoted at its right hand end in-Figure 3- as-at 2| l to the upper portion of arm 2l-2-. which. issecured at its lower end to shaft 2l3-mounted in bearings 2M and 2 i5 which project out from supporting members II and I0 respectively. Between shaft 213' and point 2 a suitable lug" 2| 6 is pivoted to vertical arm- 212- as; at- 2H, said lug 216 hasthreadably secured thereto a rod'2 #8- which is threadably secured" at-its other end to a suitable turnbuckle 2l9. Threadablymounted in the other end of turnbuckle 219' is rod 220 which isthreadably mounted inlug-22!, said lug being" pivoted to lower portionof arm member 222- as'at 223. Arm member 222 'is-secured at the upper end thereof by any suitable means such as pin or bolt 224 to bearing 40. I

Located on this arm 222 is cam follower 225 which is adapted'to travel in groove"226- of double acting cam 22'! mounted on main drive shaft 36.

It is seen that by means of turnbuckle 2|9 the position of package remover 2I0- can be adjusted relative totable member 4| in order to give the package the right position when. removed from the final position.

Figure 3 shows the package remover disposed to the right, whereas Figure 16 shows the package remover and its associated parts in another position with the package being removed to the left.

A carton 68 when removed to position as shown in Figure 16 will have a tendency to return to its previous position after package remover assumes its position as shown in Figure 3.

Suitable provision must be-made in order that package 68 as shown in Figure 16 will maintain the position to the left as shown. In order to accomplish this result suitable gripping dogs 23!) and 23! are placed on opposite sides of table 30 to engage the ends ofthe package or carton 68. These dogs are pivoted-on suitable bolts 234 which are attached to table member 30 and said bolts 23Arhave a torsion spring 232 .therearound which normally-tends toforce gripping dogs, back against pins 233. Since the distance from facegtoface ofthese-dogsisslightly less thanthe length of arcarton, the carton after: ithas' once passed between: the dogs will be prevented. frorn returning due tmthewedge-action thatcw-ill take place and hold the, carton in the positionthat, the package removerhasplaced it; f

Directly above-these closed cartons is disposed abroad plate 235 secured in positionby any suitablemeans such asstraps 236 which projectover this plate and downwardly. and. are fastened to the topof table member- 30. This plate-serves as aguide for these. packages in order to keep the packagesfrom bucklingon. the table when a large number of packa fisare lined up so the glue or adhesive will. be dried-by the time the cartons make theirappearance at the other end of plate 235.
